Attic Ductwork Condensation

When water condenses and drips into your attic or home it can cause a some serious secondary problems.

Attic ductwork condensation.

Dripping condensation may also lead to a ceiling leak which not only looks bad but also rots drywall and can cause your ceiling to collapse over time. You can convert your vented unconditioned attic into an unvented conditioned attic. So if you see unusual water staining on any of the ceilings in your home and the roofer has eliminated roof leaks it is likely coming from some fault with the duct system in your home. It s a natural process and similar to the way a chilled soda begins to sweat once you take it out of the refrigerator on a hot day.

When ductwork is touching it forms a very cold spot where they are touching thus condensation begins. It can also feed mold growth and cause ceiling joists to rot and sheetrock to disintegrate leading to unhealthy air quality in your home and the need for costly structural repairs. Over time condensation dripping from your ductwork onto attic insulation can cause it to compress which lowers its r value. For more information on this.

Even though the air conditioning equipment appears to be operating normally humidity inside the house is between 60 and 65 and return ducts located in the attic show significant condensation. The colder the air is inside the duct the greater the chance of ductwork sweating. Ductwork located in an attic must be hung properly so that the insulation can do its job. Let s say your ductwork is in your attic.

There are two main ways to solve this problem. The 1 746 square foot house has r 19 insulation between the rafters and between r 15 and r 20 of rigid foam above the roof sheathing. Condensation on air ducts can be a serious problem. You can install insulation on the attic side of the register boot and you can make sure that your duct is adequately.
